실험 절차

By the procedure of Efxample 1, a solution of p-methoxybenzyl mercaptan in dimethylsulfoxide is added slowly to a stirred suspension of sodium hydride in dry dimethylsulfoxide under nitrogen. After stirring for one hour at room temperature, 3-bromopicolinamide is added and the mixture is kept about 75°C. for three hours, then worked up by cooling, diluting with ice water, filtering off the resulting solid, washing it with water, drying and recrystallizing from aqueous dimethylformamide to give 3-(p-methoxybenzylthio)picolinamide, m.p. 252°C. (dec.).
